ERNEST L. DAVIS, OF CLEVELAND, OHIO, ASSEGNOR TO THE ACETYLENE STOVE MANU- FACTURING COMPANY, OF CLEVELAND, OHIG, A CORPORATION OF OHIO Bonner.

Application filed October 8, 192?. Serial No. 224,884.

An object of the present invention is to provide a burner for gases, and more particularly for acetylene gas, which will be inexpensive to manufacture, easy to clean, rela tively free from disorders, and extremely effi cient in opertion. A further object of the invention is to provide an improved method of manufacturing such a burner.

To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims; the annexed drawing and the following description setting forth in detail one method and one product exemplifying my invention, such disclosed procedure and product constituting, however, but one of various applications of the principle of my invention.

In said annexed drawing Fig. 1 is a plan view of a burner constructed according to the present invention; Fig. 2 is a longitudnal section thereof on the line 22 of Fig. 1; Fig. 3 is a transverse section on the line 33 of Fig. 1; Fig. f is a transverse section on the line 14E of Fig. 1; and Fig. 5 is a perspective view of one of the burner strips which are used in the pactice of the present invention.

The burner which is contemplated by the present invention consists essentially of an inlet 1 having a flared end 2 which is open at its free end and is traversed by a bar 3 provided with an aperture 4 for the reception of a supply pipe, together with a plurality of burner chambers 11 receiving burner strips 12. The burner is provided at its end opposite the flared end 2 with a projection 5 having therein a slot 6 to receive a pin (not shown), on a stove or other implement in which the burner is to be used for the purpose of steadying said burners in position. The burner proper comprises a grid made up of parallel chambers 11 spaced from each other by openings 7 and carried on the inlet tube 1. The chambers 11 are open at their tops, as indicated at 8, and are provided with projecting side walls 9 and with spaced lugs 10 projecting above the upper edges of the side walls 9. The burner is preferably made of cast iron or some similar material and the walls 9 and lugs 10 are characterized by certain elasticity.

The open top 8, of each chamber 11, is adapted to receive a pair of mating burner strips 12. Each of these strips is formed with ears 13 at its opposite ends and with cavities or depressions 1 1 separated from each other by a stiffening partition 15 and defined by said partition 15, the end walls 18, and the upper edge 20 of the strip. At its upper end the partition 15 widens into a lug 16, and a similar lug 17 is provided at each side of said lug 16 intermediate said lug 16 and the respective end wall 18. Thus the end walls 18 and the lugs 16 and 17 define, when the two strips 12 are clamped together in mating relation, a pluality of burner slits 19. The particular structure described above provides a pluality of burner slits at the upper endof each of the chambers 11, said slits being of the proper proportions to provide an efficient burning of acetylene or similar hydrocarbon gas.

The combined thickness of a pair of strips 12 is slightly greater than the normal width of the slots 8. In the manufacture of the present burner, the inlet 1 and the chambers 11 are integrally cast, and thereafter the pairs of strips 12 are forced into the open ends of the chambers 11 under heavy pressure, and because of the slight difierence in width between the slots 8 and the pairs of strips 12, the walls 9 and lugs 10 of the chambers 11 are forced slightly apart, and are thus put under a strain. @bviously, therefore, the natural elasticity of the metal tends to force the side walls 9 and the lugs 10 toward each other, thus clamping the pairs of strips 12 tightly in position.

Other forms may be employed embodying,

the features of my invention instead of the one here explained, change being made in the form or construction, provided the elements stated by any of the following claims or the equivalent of such stated elements be employed, whether produced by my preferred method or by others embodying steps equivalent to those stated in the following claims.

I therefore particularly point out and distinctly claim as my invention 1. its was at maximising mans which comprises forming a grid having a central gas inlet, and a chamber branching therefrom, said chamber being open at its top, forming a pair of separate burner strips, the combined thickness of said strips being slightly greater than the width of the open 7 top of said chamber,and pressing said strips into the open top of said chamber.

2. The combination with a grid having a gas inlet and a plurality of slots in communication therewith, of a pair of separate mating burner strips clamped in each slot by the natural resilience of the material of the slot walls.

3. A gas burner comprising a slot, and a removable elongated tip therein consisting of a pair of strip members held therein and in mutual contact by friction, and extending partially above the top of said slot, each of said strip members having an inner face and spacing projections extending therefrom, certain of said projections forming closures between the ends of said strip members, said faces and the projections thereon defining gas passageways.
